CUSHION STRUCTURE.

To all whom it may concern: 1

Be it known that I, FRANK ,P. D"ARCY, a.

citizen of the United States, residing at Kalamazoo, Michigan, have invented "certain new and useful Improvements in Cushion Structures, of which the following is a specification.

This invention relates to improvements in cushion structures. v

My improvements are particularly :de-. signed by me for automobile .seat back cushions and I have shown the same rembodied in such a structure. They are, how- I accomplish the objects of my invention by the devices and means described in the following specification. p The invention is clearly defined and pointed out in the claims.

A structure which is a preferred sembodi-. ment of my invention-is clearly illustrated in the accompanyingdrawing forming a part of this specification, in-which:

Figure I is a front perspective viewof an automobile body embodying the features .of

' my invention before the upholstering is applied tothe seat backs. Fig. II vis an enlarged detail section'showing one of the attaching clips as employed in Fig. I. Fig. III is a plan viewof one of the attaching clips. Fig. IV is a detail vertical section through a back structure with the upholstering in position thereon. Fig. Vis an en largeddetailsection of a modified structure, the modifications being'in the means for securingthe border spring. .Fig. (Lisa-dc Specificatinnoi Lettersfetent.

Fig. VIII 1s a detail transverse section on aline cor responding to li-ne 8'8 of Fig. V I. Fig. {IX 1s a detail plan view -showinjg still another modification of the attaching means. Fig.

'Referningtofthie drawing, l represents an: automoblleibody havin'g seats provided'vv ith back itop rai ls 2 and =side top rails 3; These top rarls are' :Ior convenience-made upof-sections. The details of the seat body form no :part of my present invention and are therefore not fi'uther described. On thetop of :the rails I mount-the coiled band border springs 4a, the springs prefera b'ly being continuous around the back, that is, a single spring is extended from the front end of one .arm'around the back to the fr'ontend of theother arm. The ends' of thesprings are secured rigidly by emean's of nai-ls -at {51 A" part of the .coils' are attached bymeans -o'f clips :6, which have opposed tojfigues 71 adapted :to engage the :coils, ithe clips ibeing' perforated 'a'ti8 .to @receive"tlreznails9. -Se'e; F 1gs. II and III. These clips'engage' tl1e' coils so thatithey "have a sliding "movement,

thatuis, they are free itokmovefispi rally and V this-allows the springs to yield when pres sure is exerted :thereonr; I also preferably mount a :border spring110 on the front for inner side of the top rails. The border spring d0 .is of a less diameter than #the top border :spring. The cushion body :springs 11 -are:mounted on-the back frames to sup-' port theupholstering comprising an inner back and extended over "the border springs and secured to thezrearside of .the top zrail, as shown :in' Fig. IV. The covering is-pref-' erably provided with a fillingof curledfhair and is tuftedaas is :customary;

a covering 12 arranged-overthebody springs and secured to the bottom piece 113 ofithej use on the back or arms of chairs, sofas and the like, and may be applied to seat cushions. It is particularly advantageous however for back cushions.

In the modification shown inFig. V the spring is incased in a tube 20, which is drawn down into attaching webs 21.

In Figs. VI, VII, and VIII, I have illustrated a metal attaching strip 14 having attaching loops 15 struck up therefrom atintervals to engage spaced coils, as in Fig. VI,

there being a loop everyfourth coil in the figure illustrated. The attaching strip is notched at 17 so that it may be bent around the corners in applying it to the frame. The advantage of the clip 6 is that the clips may be placed and the springs attached to any frame while the attaching strip 14 should.

be made of the proper length for the particular frame. The loops 15 have sliding engagement with the coils so that they are free toslide therein.

In the modified structure shown in Figs. IX and X ordinary staples 18 are employed for attaching'the coils. These staples are preferably not driven in far. enough to clamp the coils but to permit the sliding movement of the coils therein.

My improved border spring is very economical to produce and may be quickly applied resulting in a considerable saving of labor in the upholstering of a structure such as anautomobile back and also in a saving in the fillingmaterial or curled hair, and further, the structure eifectively maintains its shape. a Y

I have illustrated and described my improvements in a satisfactory embodiment and in certain modifications, thereby showing the generalapplication thereof. I have not attempted to illustrate or: describe various other modifications and adaptations which I contemplate as I believe the disclosure made will enable those skilled in the art to which my invention relates to embody or adapt the same as may be desired, and I desire to be understood as claiming my invention specifically as well as broadly within the scope of the appended claims.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. In a structure of the class described,

comprising back and side portions provided with top rails, the combination of spirally coiled band springs disposed on their sides on the front and top of said top rails, the ends and a part of the coils of said springs being secured to said rails, the securing means for the coils permitting movement of the attached coils in the direction of their spirals, cushion body springs disposedbelow said top rails, and an upholstering covering extending over said body andlrail springs.

2. In a structure of the class described,

comprising back and side portions provided with top rails, the combination of a spirally coiled band spring disposed on its side on said top rails, the ends and a part of the coils of said spring being secured to said rails, the securing means for the coils per-. I

mitting movement of the attached coils in the direction of their spirals, cushion body springs disposed below said "top railspand an upholstering covering. extending over] said body and rail springs.
